Literally, the bank found that the card transaction was abnormal, so it restricted the transaction. Details can be confirmed by calling the bank's customer service hotline. Sometimes the transaction frequency is too high, and the transaction exceeds the limit of the merchant, which may lead to the inability to trade.

According to the problem description, it should be that the cardholder has a risk problem in the process of using the credit card, which leads the bank to monitor its consumption.

If the credit card is lost, stolen, maliciously overdrawn or violates the credit card laws and regulations, in order to ensure the interests of customers and banks, cardholders or banks can monitor the credit card or even stop the payment of the credit card (that is, temporarily freeze it).

Stopping payment by credit card only closes the transaction function of credit card. If there is a payable amount in the account, the cardholder should make repayment as usual, and can receive repayment normally after the credit card stops paying.
